Extracellular Signal Regulated Kinase (ERK) plays an important role in multiple cell signaling processes, by catalyzing the phosphorylation of a variety of substrates. The enzyme itself is activated by phosphorylation at two different sites by a second enzyme called mitogen-activated protein kinase kinase (MEK).
